Abstract

The invention discloses a colorful color filtering film, a colorful color filtering film display unit and an array structure of the colorful color filtering film. The colorful color filtering film display unit comprises two transverse pixel units and two longitudinal pixel units, the transverse pixel units and the longitudinal pixel units are arranged in a 2*2 array mode, each row and each line are respectively provided with one transverse pixel unit and one longitudinal pixel unit, each transverse pixel unit comprises red sub-pixels and green sub-pixels, the red sub-pixels and the green sub-pixels are arranged in a left-and-right mode, each longitudinal pixel unit comprises fourth-color sub-pixels and blue sub-pixels, a fourth color is one of the colors except for the three primary colors, and the fourth-color sub-pixels and the blue sub-pixels are arranged in an up-and-down mode. The array structure of the colorful color filtering film is formed by a matrix composed of the colorful color filtering film display units, and is arranged on the colorful color filtering film. According to a four-primary-color sub-pixel display unit structure, the resolution can be effectively improved, the fourth-color sub-pixels are additionally arranged on the basis of the three primary colors, the display color gamut is improved, and displayed colors are abundant.

Description

technical field

[0001] The invention relates to a color liquid crystal display technology, in particular to a color filter film, a color filter film display unit and an array structure thereof. Background technique

[0002] The color filter array (ColorFilterArray, CFA) is a key factor affecting the resolution and color performance of liquid crystal displays. In the prior art, most of the color filter arrays of liquid crystal displays and white OLED displays use red, green, and blue primary color sub-pixels to form basic display units, and the basic display units form an array to form a color filter array that covers the entire area. display screen. Figure 8 It is a structural representation of the first scheme of the color filter film display unit in the prior art, as Figure 8 As shown, the display unit 10' includes three sub-pixels of red R, green G, and blue B arranged horizontally, and the display unit 10' is arranged on the color filter film in the form of a matrix ar...
